WEIGHT-EQUALIZATION DEVICE.

Application filed December 7, 1920. Serial No. 428,872.

7 '0 all whom it may concern:

Be it known that l, GEORGE H. F. HOLY, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new. and useful Improvement in Weight- Equalization Devices, of which the following is a specification.

My invention relates to transformers apd it has particular relation to weight-equalization devices therefor.

One of the objects of my invention is to provide a Wheeled base for a transformer whereby the total weight of the same may be uniformly distributed among a plurality of wheels or rollers and thus automatically accommodate itself to irregularities in the track.

Another object is to provide a device of the character designated that will comprise relatively few parts, may be quickly and easily assembled and strong and rugged in structure.

Briefly stated, my invention comprises a main-frame structure upon which the transformer is mounted. Additional frame members, each of which carries a plurality of wheels, are pivotally mounted upon the main-frame structure. The wheel-carrying frames are thus independent and are separately movable about horizontal pivotal connections.

lleretofore, in structures of this type, the wheels, usually four in number, were mount ed directly upon the main transformer-supporting frame and were immovable, in a vertical direction, with respect to each other.

By means of my invention, each wheel may move vertically with respect to any other wheel to accommodate itself to track irregularities or obstructions and, at the same time, to support its share of the load.

In the accompanying drawing,

Fig. 1 is a. side elevational view of a transformer and a weight-equalization device constructed in accordance with my invention.

Fig. 2 is an end elevational view of the structure illustrated in Fig.1.

Referring to the drawing, a transformer l is mounted upon a frame structure, preferably comprising a plurality of parallel spaced beams or channel bars 2 disposed in pairs adjacent to each side of the trans.

additional former. A plurality of trucks 3 are pivotally mounted, as at 4, between the beams 1 of each pair. Each of the trucks 3 preferscribed, each truck may swing about its,

pivotal connection and between the channel bars 2 in a vertical plane to accommodate it self to irregularities of the track level and to insure, at all times, an equal distribution of the weight of the transformer upon the wheels and track.

I claim as, my invention:

l. The combination with a transformer, of a main supporting frame comprising a plurality of pairs of spaced members, a plurality of wheel frames pivotally mounted be tween the members of each pair for independent pivotal movement with respect to said frame. l r v I 2. The combination with, a transformer, of a main supporting frame comprising a plurality of pairs of spaced members, a plurality of wheel frames pivotally mounted between the members of each pair for vertical pivotal movement with respect to said frame.

3; The combination with a transformer,

of a main supporting frame comprising a plurality of pairs of spaced members, a plurality of supporting trucks pivotally mounted between the members of each pair for vertical pivotal movement with respect to said frame, said trucks comprising a plurality of spaced frame members having wheels mounted therebetween.

4. The combination with a transformen supporting frame, of a plurality of spaced frame members, a plurality of independent and separately movable wheeled trucks pivotally mounted between certain of said members, said trucks each comprising a plurality of side members having wheels disposed therebetween.

In testimony whereof, I have hereunto subscribed my name this 30thday of November, 1920.

GEORGE H. F. HOLY.
